In practice, a PUR Edgebanding process works like this: The machine’s PUR gluing unit heats the adhesive to about 120–150 °C, applies a thin bead or layer to the panel edge, and presses the pre-glued tape against it.
As the PUR cools, the bond forms; then over the next hours (and up to 48 hours full cure) the moisture reaction solidifies the joint. The result is an exceptionally strong, durable bond that is resistant to solvents, steam, and temperature swings.
PUR adhesives are formulated as 100% solids (no solvents) and are available in various forms (blocks, granules, or cartridges). They must be kept dry until used, and during application the machine must maintain the right temperature.
Because PUR cures slowly after application, it has a longer “open time” than EVA. It allows slight repositioning of tape if needed.
Its curing chemistry is irreversible – once bonded, the adhesive will not soften with reheating. As Neoflex explains, PUR hot-melts “react with the moisture… giving the product high resistance to temperature and extreme environmental conditions”.
In summary, PUR Edge Banding offers a chemically bonded, waterproof edge seam. It is widely used in cabinetry, furniture, and other panel processing where edge quality and durability are paramount.
PUR’s high adhesion allows you to use much less glue per joint. The glue line is extremely thin – often imperceptible. For visible-edge products (like glossy cabinets or light laminates), this minimal seam is a major aesthetic plus.
In comparison, EVA glue lines tend to be thicker and more opaque. Casa Custom notes that with PUR “the amount of glue used will be about 1 times less, and the glue line is less obvious”.
In other words, PUR allows virtually zero-line finishing, enhancing the appearance of high-end cabinetry.
It may seem counterintuitive since PUR costs more per kilogram, but it often saves time and money in the long run. PUR cures faster to handling strength, which shortens cycle times. Workers can finish and deliver parts sooner.
Also, because PUR needs less adhesive per joint, suppliers report material cost savings. In practice, you might use 30–50% less PUR by weight than EVA for the same job.
In addition, the long-term reliability of PUR bonds means less rework, scrap or warranty issues – all of which improve overall profitability.
Laser bonding is extremely fast and clean. There is no drying time or waiting – the bond is instantaneous as the panel passes under the laser. There are also no fumes or solvent emissions, and no cleaning of glue pots. Laser systems produce no volatile glue pollution, and require no cleanup, saving energy and maintenance
PUR systems, while much cleaner than solvent glues, still need occasional maintenance of the glue pot and can produce some odor during application.
You can trim, flush, and profile the PUR-banded edges just like EVA edges – usually immediately on the same machine. In fact, many CNC edgebanders auto-trim the tape flush with a router, plane, and scraper.
Because PUR does not re-soften, finishing tools should be sharp to cut the cured PUR film cleanly. Be aware that fully cured PUR is harder than EVA, so if post-processing manually (e.g., hand scraper), use carbide blades.
At the end of each shift, remove residual PUR from the glue pot and nozzles. While still warm (not scalding hot), scrape or wipe out as much cured glue as possible. Most machines allow you to dump the melt and flush with cleaning sticks or IPA-based solvents if needed. Emptying and cleaning the pot prevents old adhesive from charring or contaminating fresh glue
Homag is a market leader in edge banding. The EDGETEQ S-200 is a popular single-sided model that comes standard with a precision gluing unit for PUR. It feeds at 8–11 m/min and handles 6 mm edge thickness up to 60 mm panel height. Its SGP glue pot supports both EVA and PUR (Homag lists “processing of PUR-glue” as standard). The machine’s airTec option can even do zero-joint (laser-like) bonding.
In summary, the S-200 is an excellent entry to mid-range edgebander: compact, user-friendly, and capable of consistent PUR operation. (For details, see our Edge Banding Machines page.)
This SCM Olimpic 500plus is engineered for EVA, PUR, and hot-air processes. SCM advertises that its SGP glue pot allows “use of EVA and PUR glue with simple and quick changeovers”. It has a hefty pressure zone and can run at 12–18 m/min – great for shops needing higher throughput. The Olimpic 500plus also supports machining of two radii and NC adjustments for fast switching between edge profiles.
In practice, its quick-glue-change design makes it ideal for jobs requiring frequent EVA↔PUR switches.
IMA Schelling Novimat Compact R3 can be ordered for PUR gluing (with IMA’s quick-lock pot system). The R3 is capable of speeds up to 25 m/min, and as IMA notes, it “handles all aspects of edge processing” on an industrial scale. It features automatic pressure and feed controls for minimal operator effort. Notably, the R3 can be outfitted with an optional laser for zero-joint finishing, making it a hybrid machine.
This means you could run both laser edges and traditional PUR edges on one line. The R3 is ideal for shops that want top-tier performance in a compact footprint.
